Barrier Wall Systems:
Absorptive noise control barriers provide maximum noise
reduction with lightweight modular panels and/or louvers.
The noise barrier system is easy to install and easy
to relocate. Panels and louvers are constructed of
galvanized steel or aluminum and finish painted
in a weather and salt resistant polyester powder
coating. The finish is also graffiti resistant and
cleanable.

Free-Standing or Elevated Panel Construction
• Allows for maximum flexibility of design and utility on the
ground or on the rooftop
• One– or two-sided sound absorption
• Steel or aluminum construction
• Perfect for retrofit installation to solve existing
noise problems
• Low-weight construction ideal for roof or
bridge mounted applications
• Designed to withstand high wind loads
All-Weather Applications
• Barrier modules are designed and built to minimize water
invasion
• Panels resist “wicking” moisture through the bottom and
are self-draining
• Exterior finishes resist harsh cleaners, common
chemicals and salt exposure
• Polyester powder coating
